Resumo: This experiment was conducted to clarify why beans in intercropping frequently yield better than in sole cropping. The parameters under investigation were soil temperature and water potential at 10 cm and 20 cm depth, air temperature at 5 cm above the soil surface (under the bean canopy), and the profile of solar radiation within the maize canopy. The results showed that after a period of drought, soil moisture under the maize stand was higher than that in bean sole cropping. Air temperature as well as the soil temperature at 10 cm and 20 cm depth were lower in intercropping than in the bean sole cropping system. The higher soil moisture and lower air and soil temperatures in intercropping were attributed to lower incidence of solar radiation at ground level and to the wind barrier formed by maize plants.

Os parâmetros estudados foram a temperatura e o potencial hídrico do solo (Ψs), a 10 cm e a 20 cm de profundidade, a temperatura do ar a 5 cm da superfície do solo (sob a copa dos feijoeiros) e o perfil de radiação solar na copa do milho. Concluiu-se que, em condições de escassez de chuvas, o solo onde se encontram as plantas de milho mantém-se úmido por mais tempo do que o cultivado com feijão em monocultivo. Nas parcelas consorciadas, a temperatura do ar e as do solo a 10 cm e a 20 cm de profundidade foram menores do que nas de feijão em monocultivo. A maior umidade e a menor temperatura do solo no consórcio são atribuídas à menor incidência da radiação no solo e à barreira ao vento formada pelas plantas de milho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPortes, Tomás de AquinoGuimarães, Cleber MoraisAidar, Homero2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13795Pesquisa Agropecuaria Brasileira; v.23, n.2, fev. 1988; 169-173Pesquisa Agropecuária Brasileira; v.23, n.2, fev. 1988; 169-1731678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13795/7833info:eu-repo/semantics/openAccess2014-09-05T19:04:08Zoai:ojs.seer.sct.embrapa.br:article/13795Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-05T19:04:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
